Okay I have a NZXT H440 PC case with stock fans,and a tower cooler for my CPU.Sometimes when I boot up my system,it releases a buzzing noise from the front panel of the PC.Everything is cleaned and the temps are fine.My question is,what's causing the buzzing noise to come and go?
 
Solution
Could be as simple as the bearing in the fan is going, or it's slightly off kilter. Depending on how old the fans are. Doesn't necessarily mean that it's going to die or anything. My now 3 year old Cougar fans start doing it sometimes as well.

Also, if you take your fans out of the case to clean them, it could be that you didn't screw it in tight enough again and it's just vibration you're hearing.
